Calculation on date profile fields

[qpurser]

WOW.... Thanks so much.
Works perfect now.

As I am a complete beginner with coding I just want to share my full block code for those who are not that familiar either. Don't know if it is perfect but it gives me the right display:

$field1 = "2012-09-02";
$field2 = "2007-09-02";
$text1  = "TCMAS membership expires in  ";
$text2  = " days!";

$last_meeting = strtotime($field1);
if (($t = strtotime($field2)) AND ($t > $last_meeting))
{
    $last_meeting = $t;
}
if ($last_meeting)
{
    $days_left =  intval(365 - ((time() - $last_meeting) / 86400)) + 1;
    
}
if (!isset($days_left) OR $days_left < 0)
{
    $days_left= "TCMAS membership expired";
}
else
{
  $days_left=  ($text1.$days_left.$text2);
}
return  $days_left;
